HARRY H. HODGMAN', OF NASONVILLE, RHODE ISLAND.

SHUTTLE-CHECK.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed May 8, 1916. Serial No. 96,220.

To all whom it may concern:

Be it known that I, HARRY H. HODGMAN, a citizen of the United States, residing at Nasonville, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Shuttle-Checks, of which the following is a specification.

My present invention pertains to shuttle checks; and it contemplates the provision of a shuttle check designed more especially for use on box looms and constructed with a view to being readily placed in position and to assisting, at least, in its retention 1n proper working position.

The invention also contemplates the provision of a shuttle check constructed with a view to adequately cushioning and checking shuttle during movement into the box and forcing the shuttle back to a certain extent so as to render free the operating parts of the box and thereby allow the box to properly function.

Other objects and advantageous features of the invention will be fully understood from the following description and clanns when the same are read in connection with the drawings, accompanying and forming part of this specification in which: I

Figure 1 is a view, on the line 11 of Fig. 2, showing the check properly positioned relative to the packing box of a loom. F g. 2 is a front view taken on line 22 of Fig. 1 and showing in addition the picker and the picker stick. Fig. 3 is a front View of the body of the check. Fig. 4 comprlses disconnected perspectives of the elements that support the spring and serve forthe connection of the upper end of the cush1oning strap. Fig. 5 is a detail view of the bolt through which the spring plate is connected with the body. Figs. 6 and 7 are views of details.

Similar numerals of reference designate corresponding parts in all of the vlews of the drawings.

In Fig. 1, 1 is the end of a shuttle drop box of usual construction. 2 is a portion of a shuttle in the box, and 3 is an ordinary picker. At 4 is the end Wall of a packlng box and at 5 the top of the side wall of said box. 6 in Fig. 2 is the picker stick.

Comprised in my novel check is a body 7. This body is made up of a plate 8 and an arm 9 that depends from the plate and serves at 10 for the connection of the lower end of a cushioning strap 11. The said strap 1s carried upwardly and rearwardly over a lateral support 12 on the plate 8 and is connected at its upper and outer end with the means for holding it under tension.

Mounted in a transverse aperturc'of the body plate 8 is the threaded stem of a bifurcated bolt 13, and secured by a cotter pin in the bifurcation of the bolt is which engages the packing shown in Fig. 1. A nut 15 the stem of the bolt 13, and when said nut is loosened the spring plate can be set against the packing box, and when the nut is tightened the spring plate will be secured in said position. In the preferred embodiment of my invention the cushioning strap 11 is provided at its side toward the shuttle with a reinforcing strap 11*, of leather or other suitable material. however, is not of the essence of my invention and may therefore be omitted in the discretion of the manufacturer.

he means for effecting connection between the upper end of the strap 11 and the body plate 8 is best shown in Figs. 2 and 4. It comprises a member 20 and a member 21. The member 20 is opposed at one end to the side of the plate 8 and is provided in said end with a threaded socket 22 to receive a connecting bolt 23. The said member 20 is reduced at 24- to enter the tubular portion 25 of the member 21, and is further reduced at 26 and provided with an aperture 27 In addition to the tubular portion 25, the member 21 is provided with a flange plate 27"* and an overhanging arm 28; the latter being spaced from the tubular portion 25 to accommodate the torsion spring 29 and being aperturecl at for the connection of the strap 11. The spring 29 is connected at 30 to the member 20 and is coiled about the members 20 and 21, and has its opposite end arranged in front of the overhanging arm 28 as illustrated. Consequently the tension of the spring will be increased when the member 20 is turned in the proper direction by a wrench applied to its end portion 26 which is preferably angular; the said turning being effected when the screw 23 is loosened, and the screw being tightened subsequently to said operation to prevent casual turning of the member 20. A cotter pin 30 passed through the aperture 27 and arranged against the flange 27 is preferably employed to hold the members 20 and 21 together.

box as clearly is mounted on This reinforcing strap,

a flat spring 14 mil At 31 on the front of the body arm 9 a hunter, of cloth, iiber or other material, may be employed. The said bunter prevents the shuttle passing too far through the shuttle box, and precludes the possibility of what is popularly known in the art as shuttle smash.

In the practical use of my improvement it is unnecessary to provide means "for fas tening the check in position. This will be understood when it is stated that the plate 8 overhangs the edge of the arm 9 and constitutes means for supporting itself on the top of the packing box, the arm 9 resting within said box and against the end wall thereof. Thus by its own weight, assisted by the spring plate which grips the end of the packing box, the check is retained in proper position. hen deemed necessary, however, the body arm 9 may be bolted at 33 to the end wall of: the packing box. This fastening, it is to be noted, is not necessary, and should it give way no damage will result because of the described self-holding capacity of the check.

The described oii'set arrangement of the plate 8 is also advantageous because it renders it feasible to employ a broad and durable strap 11.

In operation, the shuttle 2 in flying into the box strikes the picker 3, and forces same against the straps 11 and 11 and also against the hunter 31. The shuttle is checked by the strap 11 and the tension means to which the same is attached, and is forced backwardly to a certain extent so as to leave the operating parts of the box free to properly Work.

Having described my invention, what I claim and desire to secure by Lettcr a spring-plate carried by said body and disposed outside said wall and grasping the exterior of the box, and shuttle checking means carried by the body.

2. In a loom, the combination of a packing box, a shuttle check body comprising an oiiset plate resting on the side wall of the box, and a depending arm resting in the box and against the end wall thereof", a spring plate connected with said plate of the body and resting outside said end wall and grasping the end of the box, and shuttle checking means arranged in front of the body arm and connected with said arm and the plate of the body.

8. The combination in a loom, of a pack ing box, and a shuttle-check resting in and on said box and having a spring portion grasping the exterior of the box to assist in holding the check in position.

In a shuttle check, the combination oi a body having a plate and an arm depending therefrom, a bolt connected with and extending laterally from said plate, and a spring plate connected with the bolt and constructed and arranged to grasp the packing box of a loom.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
